用phasr3开发微信小游戏的话, 需要修改源码的地方不多。
1:微信小游戏不支持xml,需要装个DOMParser http://club.phaser-china.com/topic/5b1276a0484a53dd723f42ff
2:图片加载方式需要修改,不好重写代码,需要修改源码
var ImageFile = new Class({
Extends: File,
initialize:
function ImageFile (loader, key, url, xhrSettings, frameConfig)
{
this.isWX = typeof wx !== "undefined";
var extension = 'png';
var normalMapURL;
if (IsPlainObject(key))
{
var config = key;
key = GetFastValue(config, 'key');
url = GetFastValue(config, 'url');
normalMapURL = GetFastValue(config, 'normalMap');
xhrSettings = GetFastValue(config, 'xhrSettings');
extension = GetFastValue(config, 'extension', extension);
frameConfig = GetFastValue(config, 'frameConfig');
}
if (Array.isArray(url))
{
normalMapURL = url[1];
url = url[0];
}
var fileConfig = {
type: 'image',
cache: loader.textureManager,
extension: extension,
responseType: 'arraybuffer',
key: key,
url: url,
xhrSettings: xhrSettings,
config: frameConfig
};
File.call(this, loader, fileConfig);
// Do we have a normal map to load as well?
if (normalMapURL)
{
var normalMap = new ImageFile(loader, this.key, normalMapURL, xhrSettings, frameConfig);
normalMap.type = 'normalMap';
this.setLink(normalMap);
loader.addFile(normalMap);
}
},
/**

* This method controls what extra work this File does with its loaded data.

*/
onProcess: function ()
{
let url = this.__url;
this.state = CONST.FILE_PROCESSING;
this.data = new Image();
this.data.crossOrigin = this.crossOrigin;
var _this = this;
this.data.onload = function ()
{
if (!this.isWX) {
File.revokeObjectURL(_this.data);
_this.onProcessComplete();
} else {
this.addToCache();
}
};
this.data.onerror = function ()
{
if (!this.isWX) {
File.revokeObjectURL(_this.data);
} else {
console.log("||||||");
}
_this.onProcessError();
};
if (this.isWX) {

}

*/
addToCache: function ()
{
var texture;
var linkFile = this.linkFile;
if (linkFile && linkFile.state === CONST.FILE_COMPLETE)
{
if (this.type === 'image')
{
texture = this.cache.addImage(this.key, this.data, linkFile.data);
}
else
{
texture = this.cache.addImage(linkFile.key, linkFile.data, this.data);
}
this.pendingDestroy(texture);
linkFile.pendingDestroy(texture);
}
else if (!linkFile)
{
texture = this.cache.addImage(this.key, this.data);
this.pendingDestroy(texture);
}
}
}); 3: 边界面部导致微信小游戏的点击事件失效, window.pageXOffset为undefined 修改源码或修改适配器都可以
updateBounds: function ()
{
var bounds = this.bounds; var clientRect = this.canvas.getBoundingClientRect(); bounds.x = clientRect.left + (window.pageXOffset - document.documentElement.clientLeft || 0);
bounds.y = clientRect.top + (window.pageYOffset - document.documentElement.clientTop || 0);
bounds.width = clientRect.width;
bounds.height = clientRect.height;
},
